I've just submitted an 8x10" 184pp book of recipes to Blurb for printing and followed the detailed directions given on their recent help pages at Affinity Publisher PDF files
I found it pretty straightforward to do tbh despite this being my first serious use of Affinity Publisher - I found Blurb's own Bookwright software so cumbersome to use and like a throwback to the last century, not that I didn't hit a few issues with AP itself - not being able to constrain find and replace to selected text being the most puzzling aspect.
Looking forward to seeing the results of my efforts in print in a couple of weeks' time...

Looks like the fix is as described in the Blurb help link I posted. Think I read somewhere that MagCloud and Blurb are actually related companies. Here's a link https://blog.magcloud.com/2020/04/14/the-difference-between-blurb-and-magcloud/
 

Is your Document Setup = Facing pages? If so, export as PDF and pick in the Area pulldown All Pages instead of All Spreads in the main export dialogue.

I know this link is for blurb, but maybe Magclouds have the same issue: "The most common error we see is an incorrect inner bleed setting for pages. The inner bleed setting must be 0 points, which is different than the top, bottom, and outer bleeds. "

I hope that footnotes/endonotes support will be ready soon. Let me remind you that InDesign only added footnotes support in its 2.0 version.

Oh geez, no need for such obnoxious/negative/etc. comments.  For many of us, myself included, it REALLY is JUST this one missing feature that makes this software unusable.  We also don't need the even more BS comments saying we should've known this feature wasn't included before we purchased it.  It was presented as an alternative to Adobe.  Just not having 20+ years of prior versions to be compatible with alone would keep it far less bloated.  Many of us aren't long time users of professional level publishing software and aren't aware this feature isn't always included.  Footnotes/endnotes of been in word-processing programs I've used going back 30 years, back when the entire HD was 100 mb or less.  Never occurred to me it wouldn't be in this.

As a new user, the current behaviour is very annoying - I’m working on a 160pp double page spread and 90% is a comfortable zoom level for what I’m working on. Every time I change spread, it jumps back to 78%, and I also have to re centre the display. So time wasting - even if there were a set of buttons I could click for preset zoom levels would help - or even better, a much more flexible customised toolbar that I could add any function to like I can for, say, Microsoft office..

Welcome to the Serif Affinity Forums, @brantome.
I find that strange, too. It sounds like a bug.
